100 Charging

• To create a positive ion you must ______?

3
100 Answer Charging

• Decrease the number of electrons.

4
200 Charging

• Describe in detail why a balloon sticks to a wall
  after rubbing in on your head.

5
200 Answer Charging

• The negative charge one the balloon induces an
  electric dipole on the wall moving the like
  negative charges in the wall further from the
  balloon than the positive charges. This allows
  the balloon to stick.
